General Information
Term type II neuroblast ID (Ontology) FBbt:00100533 (Fly Anatomy)
Definition Neuroblast that asymmetrically divides to produce a large daughter neuroblast cell and a smaller intermediate neural progenitor (INP), which can produce multiple ganglion mother cells (Boone and Doe, 2008, Viktorin et al., 2011; Ren et al., 2016). Each type II neuroblast can produce multiple INPs, leading to the generation of multiple sublineages and typically more progeny than type I neuroblasts (Ren et al., 2016).[ FlyBase:FBrf0204899 FlyBase:FBrf0207387 FlyBase:FBrf0209927 FlyBase:FBrf0214289 FlyBase:FBrf0214495 FlyBase:FBrf0233706 ]
Also Known As "transiently amplifying neuroblast" ; "transit amplifying neuroblast"
Comment Bayraktar et al., 2010, show that type II neuroblasts can be distinguished from type I neuroblasts as being Deadpan-positive, but Prospero- and Asense-negative.
